Quick Overview

Flow restrictors are essential to a properly functioning RO system. Be sure to have the appropriate flow restrictor for the membrane you have. If you decide to change your membrane to a higher or lower GPD membrane, you must also replace the flow restrictor to correspond with the membrane.

A Must Have if you upgrade your membraneBy davidon 9/25/2014

Quite simple. If you upgrade your membrane, you must have the correct size flow restrictor.
The opening on the 150 is very small. I suggest blowing through the hose to see if air makes it all the way through. if not, it is clogged.

Easily installed this and a 75 gallon per day filmtec membrane to upgrade my 35 gallon per day rodi to a 75 gallon per day rodi. Still probably need more for 210 gallon tank.

It took me a while, along with BRS support staff, to figure out my auto top-off wasn't working because my Coralife RO/DI did not have one of these!

Easy to Install, Does What It SaysBy Shannonon 7/19/2012

Bought this a while back. Was very easy to install. Does what it says it will. Every time I change my membrane, I also install a new Flow Restrictor just to be safe.

I bought a used 75gpd unit of yours from a friend. He didn't have the restrictor and I have a spare 100gpd membrane. If I purchase the restrictor for a 100gpd unit can I use my membrane and produce 100gpd?

Hi Ryan,
As long as you change the flow restrictor to the 100gpd to match your 100gpd unit, you can run the 100gpd membrane.

Which line do I connect the flow restrict or to? I bought the R/O unit used, replaced all the filters including the membrane. The unit did not have a restrictor on it...

Hi Mike,
The flow restrictor always goes on the waste water line. They come in a few different varieties including some that are on the inside of the tubing. Your unit likely wouldn't have worked without one so pretty good bet its hiding there somewhere.
